The paint underneath is protected during the wrap. Unless the paint was flakey to start with, it wouldn't get damaged.
The weight added is negliable. Vinyl wrap material is not all that thick.
Picture below shows unwrapping, without residue. The CF wrap was on a Cooper S for 11 months and the owner wished a new effect, hence the removal. I started by peeling a corner back, added a bit of heat and subsequently rolled it all into a "ball". Some broke off and some didn't. Afterwards, the roof was smooth and not even sticky. All of the film's adhesion substance remained on the vinyl. The roof did not even require a wash.
M3 special paint has to be treated like a glass baby. http://www.egmcartec...he-matte-paint/
The BMW Frozen Gray M3 is the Munich automaker's new and exclusive offering only for the North American market. So exclusive that the 30 owners of the vehicle will have to sign a paint care agreement before taking delivery of their limited-edition Frozen Gray M3.
The agreement says that the warranty on the vehicle does not cover the matte paint if it is damaged as a result of negligence by the owner, environmental damages or improper repairs.
To take care of your Frozen Gray M3 – BMW suggests the following:
Never polish or wax the frozen gray paint as it could lead to a glossy surface.
If washing your frozen gray M3 in a automatic car wash choose a car wash that does not apply vehicle wax. Rinse the M3 with high pressure water to remove dirt before sending it through the automatic car wash to avoid scratches from sand, dust and other micro-particles.
Remove bugs, bird poo, tree sap, tar, fuel spills or oil immediately using a soft sponge.
Avoid strong rubbing while cleaning the frozen paint. BMW sells suitable products for maintaining the frozen paint at your local dealer.
Repairs to the paint (scratches, dents, etching) must be completed by a BMW trained body shop. Most auto body shop will not be capable of repairing the frozen gray paint.
